New model for this year (Do not check this option if this model was listed as new in last year's Gear Guide)The big brothersister to our Leopard VC 46 packs, the Leopard AC 58 packs offer larger capacity and our more rigid Air Current suspension system (same suspension as used in our Editors Choice Award winning Blaze packs). This Alpine-ready pack works with our Crampon Holster and Tool Loops and was thoroughly tested by Justin Trauma Lichter and Shawn Pepper Forry in their amazing trip through the Himalayan range. Multiple shoulder strap mounting positions allows custom torso length setting.
